Differences between windows 8 Leaked version and MSDN version (Still don't get it)
"Its a digital signature. It doesn't effect any usage of the Operating System."
32 bytes different to be exact ! Your loosing nothing !
Microsoft adds an identifier to it's ISO's to identify which organization (internal or external) leaked a copy. The WZOR version has this "identifier" cleverly zeroed out. But it is still unique and generates a different hash than the MSDN version. Once installed as a working OS, both WZOR and MSDN are identical.
So, long story short: The difference is in the ISO's, but there is no difference between the working Windows 8 installations installed from those ISO's. So relax, you're good.
here's a screen capture of the 32bytes difference
